Abstract

In order to determine the influence of interlayers of ductile metals on the overall mechanical properties of the multilayer coatings, three-dimensional numerical simulations of depth-sensing indentation tests of titanium aluminium nitride (TiAlN) hard coatings with copper, silver, aluminium and titanium ductile interlayers were performed. The contribution of ductile interlayers to altering the hardness, the Young’s modulus and H/E and H2/E ratios of the multilayer coating with respect to a monolithic TiAlN hard coating was established for the cases of composites with different number and thicknesses of interlayers.
